Systems Across Domains
Why cross-domain systems understanding matters, and a library of system-domain notes.
What It Is
Amazon Web Services (AWS) is a comprehensive cloud computing platform offering infrastructure and services. On this site, it is part of the practical toolset behind building systems that are easier to understand, operate, and repeat.

Amazon ECS
Amazon ECS is a container orchestration service for running Docker containers.
Amazon EKS
Amazon EKS is a managed Kubernetes service for container orchestration.
Amazon Route 53
Amazon Route 53 is a scalable DNS and domain management service.
AWS/cloud systems
On-demand, API-driven infrastructure is composed from modular services with explicit cost models, enabling scalable architectures through composition, isolation, and elasticity.
Distributed systems
Multiple coordinated nodes operate under partial failure, requiring replication, coordination, and fault tolerance to deliver reliable global behavior.
Infrastructure as Code systems
Declarative configurations define infrastructure state so environments can be reproduced, versioned, and managed consistently.
IT systems
Enterprise infrastructure manages identity, communication, storage, and security to ensure controlled access, reliability, and operational continuity.
Linux systems
A hierarchical, permissioned operating system manages processes, memory, and files through a kernel that enforces resource isolation, scheduling, and hardware abstraction.
Microservices Architecture (Docker, ECS, Terraform)
Designed and built a containerized, auto-scaling microservices framework on AWS — first in 2014, then revised in 2018 with EKS, ArgoCD, Helm, and GitHub...
